Item 1.     Changes in Control of Registrant

                None.

Item 2.     Acquisition or Disposition of Assets

                None.

Item 3.     Bankruptcy or Receivership

                None.

Item 4.     Changes in Registrant's Certifying Accountant

         Oppenheim and Ostrick, CPAs, former CPAs for the Company, resigned as
         auditor on April 16, 2001. Michael Johnson & Co., CPAs of Englewood,
         Colorado were engaged as auditors for the Company on April 16, 2001.

         The Change of Accountants was approved by the Board of Directors. No
         audit committee exists other than the members of the Board of
         Directors.

         In connection with audit of the most recent fiscal year and through the
         date of termination of the accountants, no disagreements exist with any
         former accountant on any matter of accounting principles or practices,
         financial statement disclosure, or auditing scope of procedure, which
         disagreements if not resolved to the satisfaction of the former
         accountant would have caused them to make reference in connection with
         his report to the subject of the disagreement(s).

         The audit report by Oppenheim and Ostrick, CPAs for the year ended
         December 31, 2000, contained an opinion which included a paragraph
         discussing uncertainties related to continuation of the Registrant as a
         going concern. Otherwise, the audit report by Oppenheim and Ostrick,
         CPAs for the year ended December 31, 2000 did not contain an adverse
         opinion or disclaimer of opinion, nor was qualified or modified as to
         uncertainty, audit scope, or accounting principles.

Item 5.     Other Events

                None.
